I just played through EYE.exe. It was a short walk through a wooded town onto a pier before drowning in water. The character was holding a dog lead that seemed to be attached to something far in the distance. Fell off the pier and a video tape fell onto my screen after I drowned.
Clicking it played some Blair-Witch-esque shots with titles talking about a break up and the word blue capitilized. Dated to 1975, the year John went missing. Not sure what it means, but the video tape had that eye symbol on it.
